3-pin Magnetic Connectors

The 3-pin magnetic connectors by GT Contact expand on the proven 2-pin design, adding a third contact for applications requiring additional signal capacity or a dedicated shielding/earth line. Like their 2-pin connector, they are built for quick, safe disconnection under tension, helping to protect both cables and connected devices from accidental damage. Their rugged design ensures they can withstand demanding conditions without compromising performance. 

The GT Contact 3-pin magnetic connector range supports a rated current of 2A at 30V AC/DC. With their 360-degree rotation capability, these connectors maintain constant electrical contact from any angle—making them ideal for wearable electronics, portable instruments, and other applications where movement and flexibility are key. 

The 3-pin version is available in IP67-rated panel-mount models with a short 4 mm flange depth and rear potting for a secure environmental seal, as well as in straight or 90-degree cable connectors. Cables can be supplied to custom lengths with blunt cut, USB plug, or user-specified terminations. 

The cable-mount connector fits 20.75 mm round or 19.2 mm x 20.75 mm D-cut openings to prevent rotation and ensure a stable connection. An optional rubber cap offers extra protection in challenging environments. While both the panel-mount and cable connectors are IP67 rated individually, the magnetic interface is not waterproof due to its breakaway function. With added versatility from the third contact, these 360-degree rotation connectors offer a highly reliable solution for power-plus-signal applications in compact, low-voltage systems.

FAQs

Magnetic connectors are a style of connector that are held in place by magnets rather than conventional locking mechanisms such as screw or bayonet. Due to this design they are very easy to connect and disconnect which is ideal for areas where cables could be damaged by accidental pulling. However, the terminations are less environmentally sealed due to the force of the magnets used.

Magnetic connectors work in the same way as a standard connector, by connecting the positive and negative pins are which creates a circuit. The difference with magnetic connectors is through their use of positive and negative magnets within the connector housing. This attraction of the opposing magnetic force pulls the two connector ends together creating the connection of the pins inside.
